Given a node of a utility service distribution network, a topology of a subset of the distribution network having the given node as a root node and one or more child nodes branching from the given node is determined. The topology may be determined based on relationships or correlations of utility usage information between the given node and a plurality of potential nodes that are considered in the topology determination. Upon determining the topology associated with the given node, the determined topology may be used to detect fraud and leakage that may occur in the distribution network on a regular basis or upon request. If fraud or leakage is detected in the distribution network, the system may schedule a follow-up and/or field investigation to investigate and fix the fraud or the leakage in the distribution network.

The invention relates to a system of consumption meters (2) arranged in a communication network, where program data of the consumption meters can be updated via the communication network. A data collector (3) is arranged for updating the program data of a group of consumption meters over the network. This is performed by establishing a dedicated update session to each consumption meter of the group of consumption meters, and transmitting addressed update program segments to consumption meters in session. During the update session with a given consumption meter, any other consumption meter which is within communication range (8) will, if it receives the update segment, store it even though the segment is addressed to another meter. In an update session of a next meter, only segments not already stored from a previous session to another consumption meter are transmitted to the next meter.
